[OS X TeX] xindy hangs on ARM

[Alexander Krumeich]

Richard and Herbert,

thanks for getting back to me so quickly. I managed to create a MWE
which you find attached. You'll also find a .latexmkrc. The weird
thing is that it compiles on the first and maybe second run. Repeated
runs of "latexmk -c && latexmk" however will put the process in the
hang state.

Richard, I feel your pain when it comes to compiling LISP. I tried it
a year ago when I wanted to build xindy for Alpine Linux. Whole
different story, but I never managed to compile CLISP. What made me
wonder, though, is that this sample and my production project run fine
in MacTeX 2020 under ARM.

Compare the output of "xindy --version" for 2020 and 2021:

MacTeX 2020:

xindy release: 2.5.1
xindy script version: 1.18
xindy kernel version: 3.0
CLISP version 2.49.50 (2017-03-19) (built on richards-mac-pro.local [10.0.1.14])
    architecture: X86_64

MacTeX 2021:

xindy release: 2.5.1
xindy script version: 1.18
xindy kernel version: 3.0
CLISP version 2.49 (2010-07-07) (built on richards-macbook-pro-4.local
[10.0.0.79])
    architecture: X86_64

It looks like that the CLISP version used for MacTeX 2020 is slightly
newer than the one in 2021. Odd, but there build dates are seven years
apart. Do you still have the 2.49.50 version? Maybe if you compiled
xindy against that version it would work.

All the best

   Alexander

Thus if there is a problem, I'll only fix it if you or someone else can provide a web page explaining exactly and mechanically how to compile Lisp using the standard XCode compilers. An instruction which begins "first download and install CMake ..." won't cut it.
